Starting and Stopping the UPS
When the inverter reaches full voltage, it turns on and supplies power to the critical load. It takes less than one minute for the UPS to achieve Normal mode.
If a bypass source is available when you turn the START switch on, the critical load is immediately supplied by the bypass source in Bypass mode until the inverter turns on and the UPS transfers to Normal mode. The status indicators on the Monitor Panel indicate when the UPS is in Bypass mode or Normal mode as appropriate.
4.1.2To Shut Down the UPS from Normal Mode
1.Turn the MODE switch to BYPASS.
The UPS switches to Bypass mode. If the bypass source is not available, the power processor remains on and an alarm sounds.
2.When the transfer is complete (the LCD screen reads “On Bypass”), move the CB1 switch to OFF.
The bypass source supplies the critical load and the power processor
4.1.3To Start the UPS in Bypass Mode
If the PPU of the UPS is not available and you need to energize the critical load right away, you can energize the critical load without the benefit of backup. To turn the UPS on in Bypass mode:
1.Turn the MODE switch to BYPASS. (The remaining switches can be in any position.)
2.Turn the START switch to the right momentarily.
Power to the critical load is supplied by the bypass source. No backup is available.
4.1.4To Shut Down Power to the Critical Load While in Bypass Mode
To perform maintenance or service on the critical load, you must shut it down first:
1.Turn off all equipment that is being powered through the UPS.
2.Press the LOAD OFF button on the Monitor Panel.
